Lightning & Esd Protection - TP-Link CPE220 Installation Manual

3. Lightning & ESD Protection
Proper grounding is extremely important for outdoor devices.
By using shielded CAT5e (or above) cable with ground wire for the
connection and the provided PoE adapter (method 1 ), you can effectively
eliminate ESD attacks. If you use the general CAT5e cable for the
connection, then it is necessary to connect the grounding terminal of the
CPE to earth ground through grounding cable (method 2 ).
The following introduction takes CPE520 as an example.
